Op

@Operator
public final class ResourceApplyAdam
extends PrimitiveOp

Update '*var' according to the Adam algorithm.

$$lr_t := \text{learning\_rate} * \sqrt{1 - beta_2^t} / (1 - beta_1^t)$$ $$m_t := beta_1 * m_{t-1} + (1 - beta_1) * g$$ $$v_t := beta_2 * v_{t-1} + (1 - beta_2) * g * g$$ $$variable := variable - lr_t * m_t / (\sqrt{v_t} + \epsilon)$$

Factory method to create a class to wrap a new ResourceApplyAdam operation to the graph.

Parameters:

scope - current graph scope

var - Should be from a Variable().

m - Should be from a Variable().

v - Should be from a Variable().

beta1Power - Must be a scalar.

beta2Power - Must be a scalar.

lr - Scaling factor. Must be a scalar.

beta1 - Momentum factor. Must be a scalar.

beta2 - Momentum factor. Must be a scalar.

epsilon - Ridge term. Must be a scalar.

grad - The gradient.

options - carries optional attributes values

Returns:

a new instance of ResourceApplyAdam

useLocking

public static ResourceApplyAdam.Options useLocking(Boolean useLocking)

Parameters:

useLocking - If `True`, updating of the var, m, and v tensors will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention.

useNesterov

public static ResourceApplyAdam.Options useNesterov(Boolean useNesterov)

Parameters:

useNesterov - If `True`, uses the nesterov update.
